Description

Die vorliegende Erfindung betrifft ein Peripheriegerät nach dem Oberbegriff des Patentanspruchs 1.The present invention relates to a peripheral device according to the Preamble of claim 1.

Die Ausstattung von Endeinrichtungen wie beispielsweise von Personalcomputern mit verschiedenen Peripheriegeräten und Datennetzanschlusseinheiten zu einem öffentlichen Telekommunikationsnetz oder zu einem lokalen Netzwerk LAN erfordert einen erheblichen Verkabelungsaufwand. Einerseits kann dadurch die gewünschte Verfügbarkeit durch eine unachtsame Behandlung einer solchen Verkabelung beeinträchtigt werden. Andererseits lässt sich nicht in allen Gebäuden die Verkabelung auf den notwendigen Stand der Technik bringen. Wirtschaftliche, praktische wie auch ästhetische Gründe lassen oft eine solche Verkabelung nicht zu.The equipment of terminal equipment such as personal computers with various peripheral devices and data network connection units to a public telecommunications network or to a local area network LAN requires a significant amount Wiring. On the one hand, this can result in the desired Availability due to careless handling of a such wiring can be affected. On the other hand, lets not all of the buildings have the necessary wiring Bring state of the art. Economical, practical as well Such cabling often does not allow aesthetic reasons.

Ein solches Verkabelungsproblem tritt auch bei der zunehmenden Nutzung von ISDN in privaten Haushalten auf: Dies bedingt aber die Führung eines vierdrähtig ausgeführten S-Busses in einer Wohnung oder in einem Einfamilienhaus.Such a wiring problem also occurs with the increasing Use of ISDN in private households on: But this requires the management of a four-wire S-bus in one Apartment or in a family house.

Die Technik einer drahtlosen Ankoppelung eines Personalcomputers, eines FAX-Gerätes oder eines Telefones ist hier eine geeignete Lösung. Mittels DECT-Technologie gemäss ETSI-Standard EN 300 175 kann eine drahtlose Kommunikation sowohl für den Sprach- als auch den Datendienst realisiert werden. So wird in [1] ein drahtloses Netzwerk beschrieben, das eine Verbindung zu einem öffentlichen Telekommunikationsnetz (PSTN, ISDN) wie auch zu einem Lokalen Netzwerk (LAN) ermöglicht. Die Empfangs-/Sendestation ist als eigenständiges Gerät ausgebildet, an dem Endeinrichtungen wie z.B. ein Telefonapparat, ein Personalcomputer oder ein Faxgerät angeschlossen werden können. Da diese Empfangs-/Sendestation im Normalbetrieb vom Benutzer keinerlei Bedienung erfordert, wird sie aus ästhetischen Gründen oft hinter einen Pult oder in einem Möbelstück "unsichtbar" versorgt. Damit geht eine wesentliche Verschlechterung der Sendeund Empfangsbedingungen einher, so müssen z.B. ein Feldstärke-Abfall oder zusätzliche Reflexionen hingenommen werden. The technology of a wireless connection of a personal computer, a fax machine or a telephone is one here suitable solution. Using DECT technology in accordance with the ETSI standard EN 300 175 can provide wireless communication for both Voice and data services can be implemented. So in [1] describes a wireless network that connects to a public telecommunications network (PSTN, ISDN) as well to a local area network (LAN). The receiving / transmitting station is designed as an independent device on the terminal equipment such as. a telephone, a personal computer or a fax machine can be connected. This one User receiving / transmitting station in normal operation Operation requires, it is often for aesthetic reasons stored behind a desk or in a piece of furniture "invisibly". This is a significant deterioration in broadcasting Reception conditions, e.g. a drop in field strength or accept additional reflections.

In der Schrift US 5,878,276 (International Business Machines Corporation) wird ein mobiler Client Computer vorgeschlagen, der als sogenannter Master ein Computersystem und Peripheriegeräte miteinander verbindbar macht und darüber hinaus mit einer "externen" Station eine Anbindung erlaubt.In US 5,878,276 (International Business Machines Corporation) a mobile client computer is proposed which as a so-called master, a computer system and peripheral devices connectable with each other and also with a "external" station allows a connection.

Für die Lösung des Problems der verschiedenen Empfangsbedingungen bei einer Funkanbindung eines Personalcomputers wird in der Schrift US 5.708,458 (Compaq Computer Corporation) vorgeschlagen, ein bereits vorhandenes Drahtgitter als Teil des LCD-Displays auch als Antenne für den Empfang von Radiosignalen dient. Die externen Radiosignale können dabei einem Gerät z.B. für ein Wireless-Lan oder einer drahtlos angekoppelten Tastatur entstammen. Dieses System bedingt jedoch, dass solche LCD-Displays mit zugehörigen Schreibstiften vorgesehen sind und kann deshalb auf andere Anzeigesysteme nicht angewendet werden. For solving the problem of different reception conditions with a wireless connection of a personal computer in US 5,708,458 (Compaq Computer Corporation), an existing wire mesh as part of the LCD display also as an antenna for the reception of radio signals serves. The external radio signals can be sent to a device e.g. for a wireless LAN or a wirelessly connected keyboard come. However, this system requires that such LCD displays are provided with associated pens and can therefore not be applied to other display systems.

In Räumen mit einer relativ grossen Anzahl von Endeinrichtungen kann sich darüber hinaus das Problem stellen, dass die verfügbaren Frequenzbänder und die verfügbare Bandbreite für die einzelne Endeinrichtung knapp wird und sich für den Benutzer als nachteilig erweist. In [2] ist ein Verfahren für eine nahezu kollisionsfreie Datenübertragung in einem tragbaren, drahtlosen lokalen Netzwerk beschrieben. Auch diese Lösung bedingt ein zusätzliches externes Gerät (Adapter) zu einem portablen Computer wie z.B. ein Laptop-Gerät. Das Mitführen eines zusätzlichen Gerätes für den Benutzer ist bezüglich der Handhabung als lästig einzustufen.In rooms with a relatively large number of end devices can also pose the problem that the available Frequency bands and the available bandwidth for the individual Terminal equipment is becoming scarce and for the user proves disadvantageous. In [2] is a method for an almost collision-free data transmission in a portable, wireless local network. This solution also requires an additional one external device (adapter) to a portable computer such as. a laptop device. Carrying an additional device is annoying for the user in terms of handling classified.

Ebenfalls bekannt ist die drahtlose Vernetzung von Personalcomputern mit dem Produkt I-Gate® [3]. Durch die Verwendung des Übertragungsverfahrens "Direct Sequence Spread Spectrum" (DSSS) kann auch in Räumen mit einer relativ hohen Dichte von solchen Übertragungsvorrichtungen eine nahezu kollissionsfreie Datenübertragung erreicht werden. Nachteilig ist, dass ein zusätzliches externenes Gerät zu jedem Personalcomputer benötigt wird, das mit einem Kabel angeschlossen werden muss.Wireless networking of personal computers is also known with the product I-Gate® [3]. By using the Direct Sequence Spread Spectrum (DSSS) can also be found in rooms with a relatively high density of such Transmission devices an almost collision-free data transmission can be achieved. The disadvantage is that an additional external device to each personal computer is needed that has to be connected with a cable.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung anzugeben, die eine drahtlose Ankopplung einer Endeinrichtung an ein Netzwerk ermöglicht, keine zusätzlichen externe Adapter und damit keine zusätzlichen Kabel benötigt und einfach installierbar ist.The present invention is therefore based on the object specify a device that a wireless coupling of a Terminal setup to a network allows, no additional external adapters and therefore no additional cables are required and is easy to install.

Diese Aufgabe wird durch die im Patentanspruch 1 angegebenen Massnahmen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in weiteren Ansprüchen angegeben.This object is achieved by the specified in claim 1 Measures solved. Advantageous embodiments of the invention are specified in further claims.

Das erfindungsgemässe Peripheriegerät mit einer eingebauten Sende-/Empfangseinheit bietet folgende Vorteile:

  • Eine Endeinrichtung erfordert für die Ankopplung an ein Netzwerk keinen zusätzlichen Adapter, dieser ist funktional in einem zugehörigen Peripheriegerät, z.B. in einer Tastatur enthalten.
  • Drahtlose Ankopplung einer Endeinrichtung zu einem Netzwerk ohne zusätzliche Verkabelung. Das erfindungsgemässe Peripheriegerät wird für die Nutzung der Endeinrichtung ohnehin benötigt.
  • Einfache Installation ohne mechanische Eingriffe in die anzukoppelnde Endeinrichtung, da standardisierte Schnittstellen vorgesehen sind.
  • Da das Peripheriegerät stets von einer Person zur Interaktion mit beispielsweise einem Datenverarbeitungssystem benötigt wird, ist die im Peripheriegerät enthaltende Sende-/Empfangsantenne stets in einer guten Lage zur Sende-/Empfangsantenne des betreffenden Partnergerätes, zu welchem eine drahtlose Kommunikation erfolgt.
The peripheral device according to the invention with a built-in transmitter / receiver unit offers the following advantages:
  • A terminal device does not require an additional adapter for coupling to a network, this is functionally contained in an associated peripheral device, for example in a keyboard.
  • Wireless connection of a terminal device to a network without additional cabling. The peripheral device according to the invention is required anyway for the use of the terminal device.
  • Easy installation without mechanical intervention in the end device to be coupled, since standardized interfaces are provided.
  • Since the peripheral device is always required by a person to interact with, for example, a data processing system, the transmitting / receiving antenna contained in the peripheral device is always in a good position with respect to the transmitting / receiving antenna of the partner device in question, to which wireless communication takes place.

Fig. 1 zeigt ein als Datenverarbeitungssystem 20 vorgesehene Endeinrichtung. Als Peripheriegerät dient eine Tastatur 12 mit einer eingebauten Sende-/Empfangseinheit 27. Die Tastatur 12 ist über eine Verbindung 11 an das Datenverarbeitungssystem 20 angeschlossen. Die Tastatur 12 weist eine Antenne 9 auf, über die eine drahtlose und bidirektionale Verbindung 14 zu einem Partnergerät 19 erfolgt. Eine Maus 17 ist über eine Leitung 16 ebenfalls an das Datenverarbeitungssystem 20 angeschlossen. Die Verbindung 11 dient für die Übermittlung von Daten vom und zum Partnergerät wie auch für die Zuführung der von der Tastatur eingegebenen Daten. Das Partnergerät 19 ist mit einem Netzwerk 15 verbunden. 1 shows a data processing system 20 Terminal. A keyboard 12 also serves as the peripheral device a built-in transmitter / receiver unit 27. The keyboard 12 is connected to the data processing system 20 via a connection 11. The keyboard 12 has an antenna 9, via which a wireless and bidirectional connection 14 to a partner device 19 takes place. A mouse 17 is also on a line 16 connected to the data processing system 20. The connection 11 is used for the transmission of data from and to Partner device as well as for feeding from the keyboard entered data. The partner device 19 is connected to a network 15 connected.

Das Netzwerk 15 kann als LAN ausgebildet sein, an dem weitere Endeinrichtungen mit dem erfindungsgemässen Peripheriegerät angeschlossen sind. Es ist aber auch möglich, dass das Partnergerät 19 an ein ISDN-, an ein PSTN-Netz oder an ein Kabelnetz für TV- und Radioprogramme angeschlossen ist. Möglich ist auch eine Anschaltung an ein als Internet ausgebildetes Netzwerk, z.B. über eine 2 Mbit/s - Strecke zu einem Internet-Service-Provider.The network 15 can be designed as a LAN, on the other Terminals connected to the peripheral device according to the invention are. But it is also possible that the partner device 19 to an ISDN, a PSTN network or a cable network for TV and radio programs. It is also possible a connection to a network designed as the Internet, e.g. over a 2 Mbit / s route to an Internet service provider.

Anhand des Blockschaltbildes gemäss der Fig. 2a wird nun das erfindungsgemässe Peripheriegerät in den Einzelheiten erläutert. An einem Bus 10 sind die folgenden Einheiten angeschlossen: Prozessor 1, Speichereinheit 2, USB-Schnittstelleneinheit 3, Funksteuerbaustein 6 und Port 5 zur Anschaltung der Tasten einer Tastatur. Die Speichereinheit 2 enthält einen Festwertspeicher, z.B. Flash-PROM und einen flüchtigen Speicher RAM. Es ist auch möglich, RAM-Speicherbereiche durch sogenannte Stützkondensatoren mit Energie zu versorgen, so dass auf diese Weise ebenfalls ein Festwertspeicher gebildet wird. Die Sende-/Empfangseinheit 27 wird aus dem Funksteuerbaustein 6, einem Funkteil 7 und einem Taktgenerator 8 gebildet. An das Funkteil 7 ist eine Antenne 9 angeschlossenen. Das Funkteil 7 bezieht den Takt vom Taktgenerator 8 (Clock, Quarz).Based on the block diagram according to FIG. 2a, the invention is now Peripheral device explained in detail. The following units are connected to a bus 10: processor 1, storage unit 2, USB interface unit 3, Radio control module 6 and port 5 for switching on the buttons of one Keyboard. The storage unit 2 contains a read-only memory, e.g. Flash PROM and volatile RAM. It is also possible, RAM memory areas through so-called backup capacitors to provide energy, so that way too a read-only memory is formed. The sender / receiver unit 27 becomes radio control module 6, a radio part 7 and a clock generator 8 are formed. At the radio part 7 is one Antenna 9 connected. The radio part 7 gets the clock from Clock generator 8 (clock, quartz).

Die Übertragung stützt sich auf das von IEEE definierte Protokoll, das als Norm [4] publiziert ist. Die Übertragung selber ist sowohl für den Infrarotbereich als auch für eine Funkübertragung auf dem sogenannten ISM-Band von 2.4 GHz spezifiziert. Für das Ausführungsbeispiel der vorliegenden Erfindung wird für den sogenannten "Physical Layer" (PHY) eine Spreizbandtechnik gewählt, die Norm erwähnt dafür zwei Übertragungsverfahren:

  • i) "Frequency-Hopping Spread Spectrum" (FHSS)
  • ii) "Direct Sequence Spread Spectrum" (DSSS).
    • Das Verfahren FHSS erlaubt eine Übertragungsrate von 1 Mbit/s, während das Verfahren DSSS solche von 1 und 2 Mbit/s zulässt. Für die schaltungsmässige Realisierung des Funkteils können beispielsweise Komponenten vom Hersteller Harris Semiconductor eingesetzt werden. Dazu steht unter dem Produktnamen PRISM™ ein Chipsatz zur Verfügung. Einzelheiten können der Schrift [8] entnommen werden. Die erwähnten Komponenten weisen ein sogenanntes Bus-Interface auf. Dieses erlaubt die Anschaltung des Busses 10 an den Funksteuerbaustein 6. Für die Kommunikation mit diesem Chipsatz wird vorteilhafterweise die Funktionseinheit "Media Access Controller HFA3840 MAC" oder "HFA3841 MAC benutzt und die zugehörige Konfiguration im Festwertspeicher der Speichereinheit 2 abgelegt. Einzelheiten zu dieser Funktionseinheit sind in der Schrift [7] enthalten.The transmission is based on the protocol defined by IEEE, which is published as a standard [4]. The transmission itself is specified both for the infrared range and for radio transmission on the so-called ISM band of 2.4 GHz. For the exemplary embodiment of the present invention, a spreading band technique is selected for the so-called "physical layer" (PHY), the standard mentions two transmission methods for this:
  • i) "Frequency-Hopping Spread Spectrum" (FHSS)
  • ii) "Direct Sequence Spread Spectrum" (DSSS).
    • The FHSS method allows a transmission rate of 1 Mbit / s, while the DSSS method allows 1 and 2 Mbit / s. Components from Harris Semiconductor, for example, can be used to implement the radio part in terms of circuitry. For this purpose, a chipset is available under the product name PRISM ™. Details can be found in the document [8]. The components mentioned have a so-called bus interface. This allows the connection of the bus 10 to the radio control module 6. For communication with this chipset, the functional unit "Media Access Controller HFA3840 MAC" or "HFA3841 MAC is advantageously used and the associated configuration is stored in the read-only memory of the memory unit 2. Details of this functional unit are provided contained in the document [7].

    Für die Anschaltung der mit der Sende-/Empfangseinheit 27 versehenen Tastatur 12 an ein Datenverarbeitungssystem 20 wird in einer bevorzugten Ausführungsform ein USB-Bus eingesetzt. In Tastaturen sind sehr oft Prozessoren der Familie 8051/8031 von Intel® eingebaut. Die Ausstattung der USB-Schnittstelle erfolgt daher vorzugsweise mit einem vom gleichen Hersteller entstammenden Controller-Baustein des Typs 8x931AA oder 8x931HA. Die Ausgestaltung der Schnittstelle kann den Schriften [6] und [7] entnommen werden. Der USB-Bus weist folgende PIN-Belegung auf:

    Pin 1:
    Vcc,
    Pin 2, 3:
    Daten,
    Pin 4:
    Masse.
    In a preferred embodiment, a USB bus is used to connect the keyboard 12 provided with the transmitting / receiving unit 27 to a data processing system 20. Processors from the 8051/8031 family from Intel® are very often built into keyboards. The USB interface is therefore preferably equipped with a controller module of the type 8x931AA or 8x931HA from the same manufacturer. The design of the interface can be found in the documents [6] and [7]. The USB bus has the following PIN assignment:
    Pin 1:
    V cc ,
    Pin 2, 3:
    Data,
    Pin 4:
    Dimensions.

    Der gemäss der Erfindung zu ersetzende externe Adapter ist mit der vorstehend beschriebenen Schaltung und Anordnung im Peripheriegerät funktional integriert. Besonders vorteilhaft ist die Verwendung der USB-Schnittstelle, da für dieses Peripheriegerät "Tastatur und Adapter" nur noch konfigurationsmässige Anpassungen auf der Seite des Datenverarbeitungssystemes erforderlich sind. Dies erfolgt beispielsweise durch Installation von entsprechenden Software-Moduln wie Treiber oder Bibliotheksprogrammen des Typs DLL.The external adapter to be replaced according to the invention is included the circuit and arrangement described above in the peripheral device functionally integrated. The is particularly advantageous Use of the USB interface, as for this peripheral device "Keyboard and adapter" only configuration-related adjustments required on the side of the data processing system are. This is done, for example, by installing appropriate ones Software modules such as drivers or library programs of type DLL.

    Datenverarbeitungssysteme werden oft abgeschaltet, wenn sie während einer voraussehbaren Zeit nicht gebraucht werden. Das Einschalten eines Datenverarbeitungssystems dauert oft unangenehm lange. Je nach Prozessorleistung und eingesetztem Betriebssystem kann der Einschaltvorgang bis zu einigen Minuten dauern. Ist das Peripheriegerät ein Telefonhörer 25, ergeben sich dadurch unliebsame Wartezeiten, bis lediglich ein Telefongespräch geführt werden kann. Deshalb ist in einer weiteren vorteilhaften Ausgestaltung der Erfindung der Telefonhörer 25 zusätzlich mit einem der Stromversorgungseinheit 4 zugeordneten Energiespeicher 26 versehen, um über die Funkstrecke 14 auch bei abgeschaltetem Datenverarbeitungssystem 20 einen Anruf beantworten oder absetzen zu können.Data processing systems are often switched off when they are in use a foreseeable time. Switching on of a data processing system often lasts uncomfortably Long. Depending on processor performance and operating system used the switch-on process can take up to a few minutes. Is this Peripheral device a telephone handset 25, this results in unpleasant Waiting times until only one phone call is made can be. That is why in a further advantageous embodiment the invention of the telephone handset 25 additionally with an energy store assigned to the power supply unit 4 26 provided to over the radio link 14 even when switched off Data processing system 20 answer or place a call to be able to.

    Der USB-Bus erlaubt auch eine Versorgung der angeschlossenen Einheiten mit elektrischer Energie. Eine Stromversorgungsschaltung 4 ist mit der USB-Schnittstelleneinheit 3 verbunden. In dieser Schaltung werden die weiteren für die Energieversorgung der einzelnen Komponenten benötigten Spannungen erzeugt. Über das USB-Kommunikationsprotokoll kann das Datenverarbeitungssystem 20 angewiesen werden, den über die Schnittstelle USB der Tastatur zugeführten Energiebedarf zu regeln. Einzelheiten können der Schrift [9] entnommen werden. Eine solche Regelung kann vorteilhafterweise für das Aufladen des Energiespeichers 26 eingesetzt werden. Mit einer temporär erhöht zugeführten elektrischen Leistung kann der Energiespeicher in einem sogenannten Schnell-Lade-Verfahren rasch aufgeladen werden, damit baldmöglichst wieder eine hohe Autonomie des Peripheriegerätes Telefonhörer 25 erlangt wird. Da der USB Bus nur vier Leitungen aufweist, kann der Stecker 23 einfach ausgestaltet sein und gut in das Gehäuse des Telefonhörers 25 integriert werden.The USB bus also allows the connected ones to be supplied Units with electrical energy. A power supply circuit 4 is connected to the USB interface unit 3. In this circuit, the others for power supply required voltages of the individual components. The data processing system can use the USB communication protocol 20 be instructed via the interface USB to regulate the keyboard's power requirements. Details can be found in the document [9]. A such a scheme can advantageously be used for charging the Energy storage 26 are used. With a temporarily increased electrical energy supplied can be stored in the energy store a so-called quick-charging process can be charged quickly, so as soon as possible a high autonomy of the peripheral device Telephone receiver 25 is obtained. Since the USB bus only four Has lines, the connector 23 can be designed simply be and well integrated into the housing of the telephone handset 25 become.

    Der Telefonhörer 25 kann mit Bedien- und/oder Anzeigeelementen ausgerüstet werden, um bei abgeschaltetem und/oder vom Datenverarbeitungssystem getrennter Verbindung 11 trotzdem Anrufe zu tätigen oder eingegangene Meldungen anzeigen oder versenden zu können. Dazu wird vorteilhafterweise ein Port 5 an den Bus angeschaltet (nicht dargestellt in Fig. 3). The telephone handset 25 can be operated and / or display elements be equipped to with and / or from the data processing system disconnected connection 11 still calls Act or display or send received messages can. For this purpose, a port 5 is advantageously connected to the bus (not shown in Fig. 3).

    Die Lage der Antenne ist von besonderer Bedeutung. Das erfindungsgemässe Peripheriegerät kann auch als Videokamera zu einem Datenverarbeitungssystem ausgebildet sein. Dies ist besonders vorteilhaft, da die Videokamera meist auf oder in unmittelbarer Nähe zu einem Bildschirm plaziert ist und dadurch die Funkstrecke zu einem Partnergerät leicht in einen nahezu direkten Sichtkontakt gebracht werden kann.The location of the antenna is of particular importance. The inventive Peripheral device can also be used as a video camera Data processing system be formed. This is special advantageous because the video camera is usually on or in the immediate vicinity Proximity to a screen is placed and thus the radio link to a partner device easily in an almost direct Visual contact can be brought.

    Das erfindungsgemässe Peripheriegerät kann auch als Maus oder als Drucker vorgesehen sein. Die schaltungsmässige Realisierung wird vorzugsweise analog zu jener wie bei der Tastatur ausgeführt. Die Verwendung der USB-Schnittstelle ist besonders vorteilhaft, da diese bei den Datenverarbeitungssystemen standardisiert und dementsprechend häufig anzutreffen ist. Die Erfindung ist aber nicht auf eine Realisierung mit einer USB-Schnittstelle beschränkt, neben der bereits erwähnten Anschaltung über PCMCIA-Slots ist es auch möglich, das erfindungsgemässe Peripheriegerät durch Multiplexierung der Daten auch an dem Fachmann bekannte parallele oder serielle Schnittstellen eines Datenverarbeitungssystemes anzuschliessen.The peripheral device according to the invention can also be used as a mouse or be provided as a printer. The circuit implementation is preferably carried out analogously to that of the keyboard. The use of the USB interface is particularly advantageous because this is standardized in the data processing systems and is therefore often found. The invention but is not based on a realization with a USB interface limited, in addition to the connection mentioned above PCMCIA slots, it is also possible to use the peripheral device according to the invention by multiplexing the data even to a person skilled in the art known parallel or serial interfaces of a data processing system to join.

    Die in Fig. 2a und Fig. 3 dargestellten Funktionseinheiten können teilweise oder vollumfänglich in einem einzigen elektronischen Baustein ASIC vereinigt sein. Eine Realisierung kann beispielsweise gemäss der Schrift [10] vorgenommen werden.The functional units shown in FIGS. 2a and 3 can partially or fully in a single electronic Block ASIC be united.
